ncut_sigma

PURPOSE

Default scaling parameter employed by Gaussian kernel in minimum normalised cut projection pursuit

SYNOPSIS

function s = ncut_sigma(X,smult)

DESCRIPTION

 Input:
     (X): Data matrix
     (SMULT): Multiplier (recommended value 100)

 Output:
    (S): Default scaling parameter for NCUTPP
